Publication number: 20230184642Abstract: A method for processing a sample of a cell culture composition includes diluting the sample followed by filtering the diluted sample, wherein the dilution may be at least 10 parts by volume of a diluent to one part sample, and the filter may be a porous membrane with a molecular weight cutoff of less than 20,000 Daltons. The dilution may be carried out at a multiple-port dilution valve having a first condition and a second condition. The sample may be mixed with the diluent at a predetermined dilution ratio when the dilution valve is in the second condition.Type: ApplicationFiled: December 15, 2022Publication date: June 15, 2023Applicant: IDEX Health & Science LLCInventors: Quan Liu, John Barnacle, Eric Beemer

Publication number: 20220057032Abstract: A fluidic connection assembly and methods for quickly connecting or disconnecting a tube to a port by hand and without the use of tools. A body is adapted to receive a tube therethrough, and may have at least two sides which are hinged. Each of the hinged sides has corresponding latching portions or projections located near a lower end of the body. These projections are adapted to fit into a port or other fitting and be securely held in place. The assembly may include a tube extending through a body and through a spring located between the end of the body and the end of the tube, whereby the spring exerts a force directly or indirectly against the end of the tube and against the body, thus holding the tubing securely and sealingly engaged in the port when the assembly is connected. The body may further comprise an additional body or an adapter, and/or a cap and latch.Type: ApplicationFiled: November 8, 2021Publication date: February 24, 2022Inventors: Eric Beemer, Scott Ellis, Craig Graham, Nathaniel Nienhuis, Troy Sanders

Patent number: 11085904Abstract: A chromatography column has a column assembly that further includes a column jacket tube and a column liner tube. The column assembly is configured with end fittings that have compression limiting features and are able to withstand very high pressure, such as used in UHPLC, in conjunction with flange portions of the column liner tube that seal the column assembly. The column liner tube may be biocompatible and may have a smooth consistent inner diameter of less than 2 mm, and an inner diameter of 1 mm in particular embodiments. The end fittings for the microtube assembly may ensure durability and reliability by preventing over- or under-tightening.Type: GrantFiled: September 28, 2018Date of Patent: August 10, 2021Assignee: IDEX HEALTH AND SCIENCE LLCInventors: Daniel J. Czarnecki, Nathaniel Nienhuis, Eric Beemer, David Steckman, David Medeiros, Donald W. Pein

Publication number: 20200292108Abstract: A tubing or fitting assembly has an inner tube layer, an outer tube layer, a sleeve, a tip portion, and can have a nut. Each of the nut, sleeve, inner and outer tubing layers, and tip portion have a passageway therethrough, with at least the passageways in the sleeve, tip portion, outer tube layer, and nut adapted to allow the inner tube layer to pass therethrough or extend over the inner layer. The tip portion can be molded over an end portion of the inner tube layer and also over a portion of the sleeve. The sleeve may include a retention feature in the form of a lip which extends into the tip portion, and also a narrower portion so that the tip portion and sleeve remain coupled together. The inner and outer tubing layers can also be retained by an interference fit.Type: ApplicationFiled: April 23, 2020Publication date: September 17, 2020Inventors: Craig Graham, Eric Beemer, Scott Ellis, Troy Sanders, Nathaniel Nienhuis
